Description
BACKGROUND

Small watercraft (for example: canoes, kayaks, stand up paddleboards, and the like) are often used on waterways (streams, rivers, lakes, oceans) as a form of recreation and transportation. When not being used, small watercrafts are often stored out of the water due to their relatively small size with respect to full size boats and tendency to be easily jostled when in the water when not manned. However, many small watercrafts are large and heavy enough to be cumbersome and difficult to remove from the water by a single operator.

Docks can be configured to be a floating structure over water or a raised platform over the surface of the water (also known as a pier). Docks can provide a convenient storage solution for small watercraft. However, docks are commonly raised above the water, therefore forcing the operator to lift the small watercraft from the water and occupy otherwise usable square footage on the dock deck with the stored watercraft. Further, inverting the small watercraft so as to prevent rain water from collecting in the watercraft is often preferred. Many small watercrafts are both cumbersome to invert and difficult to secure for storage when inverted.

Therefore, improvements in watercraft storage are needed.

The support legs 116 are configured to rest on a water floor (not shown) (e.g., lake bottom) of the water 106. In some embodiments, the support legs 116 can be extendable. In some embodiments, the legs 116 can be adjustable so as to adapt to a variety of different floor surfaces and to accommodate different depths of water. In some embodiments, the legs 116 are configured to penetrate the water floor so as to further support the watercraft lift.

The extension 110 of the watercraft lift 100 is configured to pivotally attach to the pivoting assembly 112, which is mounted to the base 108. The extension 110 includes a first watercraft support 118a and a second watercraft support 118b. The first and second watercraft supports 118a, 118b are substantially similar.

Each support 118a, 118b includes an arm 120a, 120b, a leg 122a, 122b, an arm guide 124a, 124b, a leg guide 126a, 126b, an upper link 128a, 128b, and a lower link 130a, 130b.

The arms 120a, 120b are elongate rigid members. Each arm 120a, 120b, is fixedly mounted to each leg 122a, 122b, respectively. Each arm 120a, 120b is also pivotally connected to the upper links 128a, 128b and lower links 130a, 130b. Further, each arm guide 124a, 124b extends away from each arm 120a, 120b. In some embodiments, each arm 120a, 120b can include a coating/sleeve/insert 131 that aids in reducing accidental damage to the watercraft 104 while operating the watercraft lift 100. Further, the coating/sleeve/insert 131 also aids in securely storing the watercraft 104 when the watercraft lift 100 is in the raised position. In some embodiments, the arms 120a, 120b, include channels 132a, 132b disposed within each arm 120a, and 120b.

The channels 132a, 132b are configured to mount a variety of attachments, such as securing features 134 or the coating/sleeve/insert 131, within each channel 132a, 132b. The securing features 134 are configured to be used to secure the watercraft 104 to the watercraft lift 100, specifically to the arms 120a, 120b when the watercraft lift 100 is in the raised position. In some embodiments, the channels 132a, 132b are configured to hold the coating/sleeve/insert 131 to both protect and grip the watercraft 104.

Like the arms 120a, 120b, the legs 122a, 122b are elongate rigid members. Each leg 122a, 122b is fixedly mounted to each arm 120a, 120b, respectively. Each leg guide 126a, 126b extends away from each leg 122a, 122b. Each leg 122a, 122b can also be lined with the coating or sleeve 131 that aids in reducing accidental damage to the watercraft 104. In some embodiments, like the arms, 120a, 120b, each leg 122a, 122b includes channels 136a, 136b disposed within each leg 122a, 122b for receiving securing features 134, bumpers, or other attachments.

The arm guides 124a, 124b and leg guides 126a, 126b are elongate rigid members configured to aid in retaining the watercraft 104 on the arms 120a, 120b and the legs 122a, 122b when the operator is moving the watercraft lift 100 between the lowered position (see FIG. 1.) and raised position (see FIG. 2). In some embodiments, the arm guides 124a, 124b and leg guides 126a, 126b can be adjustably angled with the respect to the arms 120a, 120b and legs 122a, 122b. Further, the arm guides 124a, 124b and leg guides 126a, 126b can also be adjusted along the length of the arms 120a, 120b, the legs 122a, 122b (as shown in FIGS. 14 and 15). This allows the operator to customize the position of the arm guides 124a, 124b and leg guides 126a, 126b so as to properly interface with their particular watercraft 104.

The upper links 128a, 128b and lower links 130a, 130b are configured to pivotally connect to the arms 120a, 102b of the supports 118a, 118b with the pivoting assembly 112. Further, the upper links 128a, 128b and lower links 130a, 130b provide addition structural support for the arms 120a, 102b when moving between the lowered and raised positions.

With continued reference to FIG. 3, the pivoting assembly 112 is attached to the base 108 and to the extension 110. Specifically, the pivoting assembly 112 includes a first support pivoting assembly 138a, that corresponds to the first watercraft support 118a of the extension 110, and a second support pivoting assembly 138b, that corresponds to the second watercraft support 118b of the extension 110.

The first support pivoting assembly 138a is mounted to the base 108, specifically to the base member 109, and also attached to the first watercraft support 118a by way of the upper and lower links 128a, 130a. The first support pivoting assembly 138a includes an extension actuator 140, a pivoting cable guide 142a, and a guard 144a.

The extension actuator 140 is configured to control the movement of the extension 110 between the lowered and raised positions. In the some embodiments, the extension actuator 140 is configured to be automatically braking, thereby holding the extension 110 in the last operated position when the extension actuator 140 is not being operated. In the depicted embodiments, the extension actuator 140 is a manual winch that uses a hand crank 146 and spool 148 to control cabling which controls the movement of the extension 110. Such cabling and movement will be described herein in further detail with respect to FIGS. 4-12. In some embodiments, the extension actuator 140 is a powered actuator using an electric motor controllable by a switch.

The pivoting cable guide 142a is configured to provide a guide for cabling traveling from the extension actuator 140 to the arm 120a of the first watercraft support 118a. The pivoting cable guide 142a includes a circular guide 141a that is configured to receive a line of cabling. The pivoting cable guide 142a is attached to the upper link 128a by a pivot guide linkage 150a. The pivoting cable guide 142a pivots about a first point 152a and moves when the upper link 128a pivots about a second point 154a. The pivoting cable guide 142a moves in a direction toward the water 106 when the extension 110 is moving from the raised position to the lowered position. The pivoting cable guide 142a pivots in a direction away from the water 106 when the extension 110 is moving from the lowered position to the raised position. The pivoting cable guide 142a aids in providing a smooth, obstruction free route for cabling traveling from the extension actuator 140 to the first watercraft support 118a.

The guard 144a covers the first pivot point 152a, second pivot point 154a, and a third pivot point 156a of which the lower link 130a pivots about. The guard 144a is configured to help prevent unwanted objects from coming in contact with the portions of the first support 118a and becoming pinched near the first support pivoting assembly 138a.

FIG. 3 also shows a perspective view of the second support pivoting assembly 138b mounted to the base 108, specifically to the base member 109, and also attached to the second watercraft support 118b by way of the upper and lower links 128b, 130b. Like the first support pivoting assembly 138a, the second support pivoting assembly 138b includes a pivoting cable guide 142b. The pivoting cable guide 142b includes a circular guide 141b that is configured to receive a line of cabling. The pivoting cable guide 142b is attached to the upper link 128b by a pivot guide linkage 150b. The second support pivoting assembly 138b shares many substantially similar parts with the first support pivoting assembly 138a. For clarity and conciseness, such shared parts are shown in the drawings on the second support pivoting assembly 138b with the reference number used to described the parts of the first support pivoting assembly 138a, described above, followed by a “b” notation. However, instead of the extension actuator 140 of the first support pivoting assembly 138a, the second support pivoting assembly 138b includes a fixed cable guide 158. The fixed cable guide 158 is configured provide a smooth, obstruction free route for cabling traveling from the second watercraft support 118b to the linkage 114.

The linkage 114 is configured to transfer the moving energy from the extension actuator 140, which is mounted to the first support pivoting assembly 138a, to the second support pivoting assembly 138b that acts to rotate the second watercraft support 118b. The linkage 114 therefore allows the first and second watercraft supports 118a, 118b to move in unison. The linkage 114 includes a first spool 160a, a second spool 160b, a shaft 162, and optionally a shaft housing 164. The linkage 114 is mounted to the base 108.

The spools 160a, 160b are configured to receive cabling and configured to rotate to either release cabling or take up cabling. In some embodiments, the spools 160a, 160b may include covers 166 that are configured to guard the spools 160a, 160b from objects coming into inadvertent contact with the spools 160a, 160b.

In some embodiments, the shaft 162 is positioned within the shaft housing 164 and fixed to the first spool 160a and the second spool 160b. The shaft 162 is configured to be rotatable about a longitudinal shaft axis. Further, the shaft 162 is rotatable in response to the rotation of the first and second spools 160a, 160b. Specifically, when the first spool 160a is rotated about the longitudinal shaft axis, the shaft 162 transfers the rotation of the first spool 160a to the second spool 160b. In some embodiments, the shaft 162 is separable and telescoping so as to have an adjustable length.

FIG. 4 shows a perspective view of the watercraft lift 100 in the lowered position, without the watercraft 104. FIG. 5 shows a right side view of the watercraft lift 100 in the lowered position. FIG. 6 shows a left side view of the watercraft lift 100 in the lowered position.

When the watercraft lift 100 is in the lowered position, the arms 120a, 120b extend generally downward toward the water 106. In some embodiments, the arms 120a, 120b are generally perpendicularly fixed to the legs 122a, 122b. In some embodiments, the arms 120a, 120b, form an angle θ with the legs 122a, 122b between about 75 degrees and about 100 degrees. The arms 120a/120b, legs 122a/122b, arm guides 124a/124b, and leg guides 126a/126b define a watercraft pocket 168. The watercraft pocket is configured to help cradle and scoop the watercraft 104 from the water 106.

As shown, when in the lowered position, the legs 122a, 122b and leg guides 126a, 126b sit just below the surface of the water 106 so as to allow the operator to easily position the watercraft 104 in the watercraft pocket 168.

Also, as shown in FIGS. 5-7, cabling is used to raise and lower the extension 110. Specifically, a first cable 170 is connected to the spool 148 of the extension actuator 140 and to the arm 120a of the first watercraft support 118a. A second cable 172 is connected to the spool 148 of the extension actuator 140 and to the first spool 160a of the linkage 114. A third cable 174 is connected to the second spool 160b of the linkage 114 and to the arm 120b of the second watercraft support 118b.

In the depicted embodiment, when raising the watercraft lift 100 after the watercraft 104 is positioned in the watercraft pocket 168, the operator rotates the hand crank 146 of the extension actuator 140. Upon such rotation of the hand crank 146, the first and second cables 170, 172 are wound around the spool 148. The first cable 170 is shortened while the second cable maintains the same length. Excess cabling of the second cable 172 previously stored on the first spool 160a of the linkage 114 is transferred to the spool 148 of the extension actuator 140.

As the excess cabling of the second cable 172 is transferred to the spool 148, the first spool 160a of the linkage 114 is rotated. The rotation of the first spool 160a causes rotation of the shaft 162, which causes rotation of the second spool 160b. As the second spool 160b rotates, the third cable 174 is shortened and excess cabling is wound around the second spool 160b of the linkage 114.

As the first cable 170 and the third cable 174 are shortened, the first and second watercraft supports 118a, 118b begin to rise from the water 106.

FIG. 7 shows a perspective view of the watercraft lift 100 between the lowered position and the raised position, without the watercraft 104. FIG. 8 shows a right side view of the watercraft lift 100 between the lowered position and the raised position with the watercraft 104. FIG. 9 shows a left side view of the watercraft lift 100 between the lowered position and the raised position with the watercraft 104.

As the watercraft lift 100, specifically the extension 110, begins to rise from the water 106, the upper links 128a, 128b, and lower links 130a, 130b begin to pivot the first and second watercraft supports 118a, 118b about the pivoting assembly 112.

FIGS. 8 and 9 show side views of the watercraft lift 100 and the position of the watercraft 104 when the watercraft lift 100 is between the lowered and raised positions. As shown, the watercraft 104 is positioned within the watercraft pocket 168 and begins to invert and the pivoting assembly 112 as the extension 110 is rotated closer to the raised position, as indicated by the arrows in the drawings. If the watercraft 104 fully inverts, the arm guides 124a, 124b are configured to catch the watercraft 104 as it moves to the stored position.

As the hand crank 146 is further rotated, the first and third cables 170, 174 are shortened further still until the watercraft lift 100 is in the raised position.

FIG. 10 shows a perspective view of the watercraft lift 100 in the raised position, without the watercraft 104. FIG. 11 shows a right side view of the watercraft lift 100 in the raised position and the watercraft 104 in a position directly before the watercraft 104 is in a secured position. FIG. 12 shows a right side view of the watercraft lift 100 in the raised position with the watercraft 104 lowered to a securing position. FIG. 13 shows a left side view of the watercraft lift 100 in the raised position.

When in the raised position, the watercraft lift 100 is configured to store the watercraft 104 in a secured position above the water and offset from the structure 102. In some embodiments, the watercraft 104 can be secured to the extension 110 so as to prevent inadvertent removal of the watercraft 104. The watercraft 104 can be secured, for example, by using straps or other similar devices attached to the extension 110. When moving into the secured position, the position of the guides 124a, 124b and 126a, 126b are configured to urge the watercraft 104 to an inverted position, shown in FIG. 11 by an arrow. As shown in FIGS. 12 and 13, the watercraft 104 is stored in an inverted position so as to prevent unwanted material (e.g., leaves, water, etc.) from collecting within the watercraft 104 as it is stored.

In the depicted embodiments, the extension actuator 140 is auto braking so as to maintain the extension 110 at its last operated position. In some embodiments, the extension actuator 140 includes a manual lock so as to allow the user to lock the watercraft lift in a particular position, specifically the raised position.

FIGS. 14 and 15 show the arm guides 124a, 124b and leg guides 126a, 126b in different positions along the arms 120a, 120b and legs 122a, 122b. Such adjustment can be made to hold a watercraft 107 of a different shape or size.

The various embodiments described above are provided by way of illustration only and should not be construed to limit the claims attached hereto.
